AUTOMATIC CORK-FULLER.

SPECIFICATION forming part of Letters Patent No. 515,411, dated February 27, 1894. Application filed May 1, 1893. Serial 110.472.651. (No model.)

To all whom it may concern:

Be it known that I, EDWIN WALKER, a citizen of the United States, residing at the city of Erie, in the county of Erie and State of Pennsylvania, have invented certain new and useful Improvements in Automatic Cork- Pullers; andI do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters of reference marked thereon, forming part of this specification.

My invention consists in the improvements in automatic cork-pullers hereinafter set forth and explained and illustrated in the accompanying drawings in which- Figure 1. is a side elevation of my improved automatic cork-puller, with the side plate removed therefrom, and the supporting standard thereof removed. Fig. 2. is a vertical central section of the same. Fig. 3. is a transverse section of the supporting standard of the cork-puller, on the line w, w,in Fig. 2,look ing in the direction of the arrow.

In the construction of my improved automatic cork-puller illustrated in the accompanying drawings A is the supporting stand ard of the cork-puller, the lower end of this standard being provided with jaws B B, in the jaw 13 I place a thumb screw 12 which engages with a plate 0, the inner end of which moves vertically between guides Ct a on the standard A, the top of the plate 0 is also provided with conical studs 0 adapted to be forced into the underside of a shelf or counter, so as to hold the standard A firmly thereon.

To the upper end of the standard A, I secure a circular case D having a tubular 'projec-tion D extending downwardly from the periphery thereof at an angle preferably of about thirty degrees from a vertical line,

and adapted to receive the mouth of a bottle, as hereinafter set forth. In line with this tubular projection D a frame E extends across the case D, slightly at one side of the center of the circular case D, so that a shaft E can be mounted in a bearing c on one side thereof, at a point coinciding with the center of the circular case D; in the upper portion Fof the herself, I bore out in line with the center of the projection D a long tubular bearing F and to the periphery of the case D I secure an arm G having a bearing G in line with the bearing F, and in these bearings F and G I mount a hollow tubular shaft H, having a groove it nearly the entire length thereof, and in the recess be tween the arm G and the upper end of the bearing F I secure a bevel pinion H to the hollow tubular shaft H, which pinion is operated by means of a bevel skew-gear wheel hereinafter described to rotate said hollow tubular shaft H and at the same time prevents any endwise movement thereof. Inside of the hollow tubular shaft H I place a corkscrew stem I provided with a spline I which operates in the elongated groove h in the tubular shaft 1-I, so that the cork-screw stem I will rotate with the tubular shaft H and at the same time slide longitudinally therein; in the lower end of the stern I is secured a corkscrew. J by means of a pin cl, so that the screw J can be removed when desired.

In guides ff formed between the upper edge of the frame E and a plate K secured to the inside of the case D, is a sliding plate L, and in one side of the projection D is arecess L cut away nearly to the lower end Zthereof, and on the lower end of the plate L is a circular boss ill (see Fig. 2, and the dotted lines in Fig. 1.) which boss is adapted to fit and slide longitudinally freely in the tubular projection D; in the center of the boss M is an opening M adapted to receive a nutN through which the cork-screw J operates, this nut is preferably made by winding a cork-screw with tinned iron wire on and then casting the nut N around it of suitable composition of metal, for example of tin and zinc, the outside of the out being formed in'amold of suitable shape to fit the opening M in the boss M; this nut, I secure in place preferably by means of a set-screw n, so that itcan be readily removed if desired. The mouth it of the projection D is also made flaring so as to conveniently fit the mouths of different sized bottles.

0n the case D I secure a catch 0 and on the face of the plate L, I pivot a bell-crank lever dog P, one arm 9 of which is adapted to engage the catch 0 when the plate L has reached its extreme downward traverse, and the other arm p'of which. is adapted to be engaged by the arm 0 of another bell-crank lever P,between the arms 9 and o of these levers is a spiral spring is which operates to actuate the dog P, to make it engage the catch 0; stops 7c and Z are secure on the plate L to limit the movement of the dog P and of the lever P; upon the plate L below the arm 0 of the lever P is secured a transverse bar or stop Q as and for the purpose hereinafter set forth.

On the end of the shaft E outside of the bearing e thereof in the frame E, I secure a crank R provided with an inwardly projecting stud 0" adapted to engage the arm 0' of the lever P and the bar or stop Q, as and for the purpose hereinafter set forth.

On the opposite side of the case D, I mount loosely a wheel R which forms a cover closing that sideof the circular case D this wheel is provided, on the periphery of its inside face, with a segment of beveled skew-gearing S adapted to intermesh with and drive the pinion H; at the ends of this segment of gearing, I provide stops r to prevent the pinion H from passing off of the segment S. The reason for the use of skew-gearing S on the wheel R with which the pinion H intermeshes, is to provide for the hollow tubular shaft H passing the bearing 6 of the transverse shaft E without interfering therewith, which shaft E is the bearing upon which the wheel R is mounted and rotates.

On the end of the shaft E outside of the wheel R, I secure an operating crank T and in the wheel R is cut a segmental recess T, and on the crank T is a boss or stud t which enters said recess T and operates when it contacts with the ends of said recess T to rotate the wheel R, and on the lower part of the case D is a boss or stop U with which a boss or stud 'u, on the inside of the crank T ongages, so that the movement of the crank in either direction is limited thereby; this stud u 1 preferably provide with a cushion m of rubber or other resilient substance, which is adapted to contact with the stop U when the crank is moved around into contact therewith.

In operating my improved cork-puller, the plate L being at its lowermost point of traverse, as illustrated in Fig. 1, the operator places the mouth of a bottle to be uncorked in the flaring mouth a of the tubular projection I) and holding it firmly therein, grasps the crank T secured to one end of the transverse shaft E and turns it around toward himself until it engages with the stop U on the case, this operates to rotate the gear wheel R which turns the pinion H and the hollow shaft H, which operates to turn the corkscrew and cause it to pass down through the nut N secured in the boss M on the end of the plate L and into the cork to be removed from the bottle; this operation has also rotated the transverse shaft E and brought the crank R secured to the opposite end thereof around, until the studrtherein has contacted with, depressed, and passed under the arm 0 of the lever P on the plate L; the operator then reversing the movement of the crank T, the stud r operating on the under side of the arm 0 of the lever P, raises the plate L together with the cork-screw without rotating the cork-screw, until the extreme upward.

traverse of the plate L has been reached, which movement draws the cork from the bottle, at this instant the stud a" on the crank R passes out from under the end of thelevero and at the same time the stud 15 engages with the end t of the segmental slot T in the gear wheel R and rotates the wheel R,the pinion H, shaft H and cork-screw stem I operated thereby in the opposite direction, so as to back the screw J up into the nut N thereby unscrewing it out of the cork just drawn and allowing it to fall out of the openlng L in the side of the tubular projection D, the plate L at the same time moving down to its normal position, again ready for operation.

Having thus fully described my invention, so as to enable others to construct and operate the same, what I claim as new,and desire to secure by Letters Patent of the United States, is
